(A)
"Energy Compensation Source" (ECS) means
a small sealed source, with an activity not exceeding 3.7 megabecquerels (one
hundred microcuries), used within a logging tool, or other tool components, to

(B)
"Field Station" means a
facility where licensed material may be stored or used and from which equipment
is dispatched to temporary job sites.

(C)
"Fresh Water Aquifer", for the purpose of
this chapter, means a geologic formation that is capable of yielding fresh
water to a well or spring.

(E)
"Irretrievable Well Logging Source" means any sealed source containing licensed
material that is pulled off or not connected to the wireline that suspends the
source in the well and for which all reasonable effort at recovery has been
expended.

(F)
"Logging Assistant"
means any individual who, under the personal supervision of a logging
supervisor, handles sealed sources or tracers that are not in logging tools or
shipping containers or who performs surveys required by rule
3701:1-49-21 of the
Administrative Code.

(G)
"Logging
Supervisor" means an individual who uses licensed material or provides personal
supervision in the use of licensed material at a temporary job site and who is
responsible to the licensee for assuring compliance with the requirements of
Chapter 3748. of the Revised Code and rules promulgated thereunder and the
conditions of the license.

(H)
"Logging Tool" means a device used subsurface to perform well logging.

(I)
"Personal Supervision" means
guidance and instruction by a logging supervisor, who is physically present at

who can give immediate assistance.

(J)
"Radioactive Marker" means licensed
material used for depth determination or direction orientation. For purposes of
this chapter, this term includes radioactive collar markers and radioactive
iron nails.

(K)
"Reasonable
Effort" means effort commensurate with an assessment, performed by the licensee
and approved by the department, of the health and safety risks of a lost source
considering the geological and hydrological location of the source, the source
type, and risks and costs of attempted source retrieval.

(L)
"Safety Review" means a periodic review
provided by the licensee for its employees on radiation safety aspects of well
logging. The review may include, as appropriate, the results of internal
inspections, new procedures or equipment, accidents or errors that have been
observed, and opportunities for employees to ask safety questions.

(M)
"Source Holder" means a housing or
assembly into which a sealed source is placed to facilitate the handling and
use of the source in well logging.

(N)
"Subsurface Tracer Study" means the
release of unsealed licensed material or a substance labeled with licensed
material in a single well for the purpose of tracing the movement or position
of the material or substance in the well or adjacent formation.

(O)
"Surface Casing For Protecting Fresh
Water Aquifers" means a pipe or tube used as a lining in a well to isolate
fresh water aquifers from the well.

(P)
"Temporary Job Site" means a place where
licensed materials are present for the purpose of performing well logging or
subsurface tracer studies.

(Q)
"Tritium Neutron Generator Target Source" means a tritium source used within a
neutron generator tube to produce neutrons for use in well logging
applications.

(R)
"Uranium Sinker
Bar" means a weight containing depleted uranium used to pull a logging tool
toward the bottom of a well.

(S)
"Well" means a drilled hole in which well logging may be performed. As used in
this chapter, "well'' includes drilled holes for the purpose of oil, gas,
mineral, groundwater, or geological exploration.

(T)
"Well Logging" means all operations
involving the lowering and raising of measuring devices or tools which contain
licensed material or are used to detect licensed materials in wells for the
purpose of obtaining information about the well or adjacent formations which
may be used in oil, gas, mineral, groundwater, or geological exploration.
